Specifically, provided are uses of a compound represented by formula (I), definitions of radical groups being described in the specifications. The compound represented by formula (I) can be used as the ligand in the copper catalyzed coupling reaction of the aryl halogeno substitute, and is used or catalyzing the coupling reaction for forming the aryl halogeno substitute having C—N, C—O, C—S and other bonds.

Synthesis of highly functionalized diaryl ethers by copper-mediated O-arylation of phenols using trivalent arylbismuth reagents

Highly functionalized diaryl ethers were prepared by copper(II) acetate mediated O-arylation reaction of phenols using trivalent organobismuthanes. The reaction is performed under simple conditions and tolerates a wide diversity of functional groups on the phenol and on the organobismuth reagent. Substoichiometric amounts of catalyst can be used by performing the reaction under an oxygen atmosphere. The N-arylation of pyridones is also reported.

Resin-bound triaryl bismuthanes and bismuth diacetates: Novel multidirectional linkers and novel resin-bound arylation reagents

A general synthesis of resin-bound triaryl bismuthanes and resin-bound triaryl bismuth diacetates starting from commercially available chloromethyl polystyrene is reported. For the first time resin-bound bismuth has been utilized as part of a multidirectional linker system for solid-phase organic synthesis and as a resin-bound arylation reagent.
